The following includes information for media representatives wishing to attend the conference and a media registration form. Introduction The 1999 Asteroids, Comets, Meteors Conference (ACM) on Cornell's Ithaca campus is sponsored by NASA, the Applied Physics Laboratory of Johns Hopkins University, the Jet Propulsion Laboratory (JPL) and Cornell. A broad range of scientific sessions will present the latest developments in all aspects of studies on asteroids, comets and meteors, including observations, theories of origin and evolution, discoveries and astrometry. For a complete list of abstracts, visit the ACM web site at http://scorpio.tn.cornell.edu/ACM/ In mid-June, a list of press conferences will be distributed, including the names and affiliations of participants. Members of the media should arrive no later than Sunday evening, July 25, because the first of the daily press conferences will begin early the following morning. The press room, in the Statler Hotel's Princeton/Yale Room on the Cornell campus, will be open daily from 8 a.m. to 8 p.m. during the meeting. Facilities will include computers, Internet access, phones, fax and copiers. Coffee, tea and Danish pastry will be served at 10:30 a.m. and at 3:30 p.m. daily.

Saturn Workshop November 2001 Presentation Meteors! Saturn Workshop Nov. 13, 2001 By Dave Gill (Below are the text portions of my PowerPoint presentation) What are meteors? • Meteors are better known as "shooting stars": startling streaks of light that suddenly appear in the sky when a dust particle from outer space evaporates high in the Earth's atmosphere. – We call the light phenomenon in the atmosphere a "meteor – the dust particle is called a "meteoroid". How big are they? • Most visible Leonids are between 1 mm and 1 cm in diameter. • A Leonid meteor of magnitude +5, (barely visible with the naked eye in a dark sky), is caused by a meteoroid of 0.5 mm in diameter and weights only 0.00006 gram. How fast do they travel? – That tiny particle can be seen over distances of hundreds of kilometers. – The reason is the astronomical speed of the meteoroids. – Just before they enter the Earth's atmosphere, Leonid meteoroids travel at 71 kps (44 mi/sec), and could travel around the Earth in 3.8 minutes! Why are they bright?

Space Science News home Meteors Down Under Debris from Halley's comet will put on a sky show for southern observers in early May May 3, 1999 : It's a fact of Nature that Koala bears, kangaroos and other denizens of the southern hemisphere rarely have a favorable view of major meteor showers. Most cometary debris streams in the inner solar system are arranged in such a way that that they tend to produce shooting stars mainly over the northern hemisphere. The well-known Leonids display is relatively easy to see from southern latitudes, but that shower is only intense at 33 year intervals when the parent comet Tempel-Tuttle passes close to Earth. Throughout the year meteor enthusiasts "down under" are able to view some of the more intense northern displays over the horizon, and there are a number of minor showers averaging 5 -15 shooting stars per hour. Without a doubt, however, the highlight of the meteor observing season is the eta Aquarids. Each year around May 5 the eta Aquarids reach their peak with 30 to 50 meteors per hour visible from below the equator. It's the best annual shower in that part of the world. Sign up for our EXPRESS SCIENCE NEWS delivery If you don't live in the southern hemisphere you might be inclined to disregard the eta Aquarids. After all there are many annual showers that are more intense and easier to view. Sky watchers at northern mid-latitudes will typically see only about 5 to 10 per hour, and above latitude 45 degrees they are practically impossible to see at all. Nevertheless, there is something special about these meteors that makes them worth watching no matter where you live. Every eta Aquarid meteoroid is a tiny piece of Halley's comet!

Asteroids Comets Meteors Terms Asteroids The Asteroid Gaspra. Asteroids are made of rocky and/or iron-nickel material and most are found in an orbit between Mars and Jupiter. Most are pitted with impact craters and dust left from collisions with other objects in the solar system. Some asteroids have other asteroids orbiting them as in the picture at right, the Asteroid Ida and its moon Dactyl. A group of asteroids orbit the sun called Near-Earth Asteroids because they are somewhat close to the Earth and occasionally may cross Earth's orbit. Could any hit the Earth?
